Rolony, 13th[edit]
- Check point
- 2hr vs. 4hr CircLigase II reaction
- Strip and re-hybridize Cy5 probe
- Start at 06/29
- Use cell dishes fixed at 07/07 --> Cells were not plenty… need to thaw new one
- GC, lysine coated dish
- Run RT : 5:00pm 07/07 ~ 9:00am 07/08 --> ~15hr.
- Run CircLigase II : S1 --> 1:30pm 07/08 ~ 3:30pm 07/08 --> 2hr.
- Run CircLigase II : S2 --> 11:30am 07/08 ~ 3:30pm 07/08 --> 4hr.
- Run RCA : 4:30 pm 07/08 ~ 12:30pm 07/09 --> ~20hr.
Result[edit]
- Not as many as before
- It could be something wrong while fixing (10% formalin once) or cells were not good.
- For the next time, I’ll do twice fixation. (37% and then 10% formalin), and cells need to be full
- Rolonies were found inside nucleus more than other area. --> it might cause from not many cells or one time fixation.
- 2hr, 4hr were not much different!
- After striping Cy3 probe, there was no signal from Cy3 channel.
- And after re-hybridizing Cy5 probe, rolonies were nicely seen through Cy5 channel.
- Rolonies were pretty stable.
- Strip protocol:
- 80% formamide in 2x SSC heated in 60C oven for 5min
- Add 200uL of 80% formamide on cells, incubate at RT for 10min.
- Wash with H2O twice, and store in PBS
